Keeping The Promise

known as the Earth Resources Technology Satellite, or ERTS. Credit: NASA’s Earth Observatory
Forty years ago this year a Botanist, a Forester, and an
EE had a Vision
Purdue’s Laboratory for the Application of Remote Sensing was the only facility capable of displaying an ERTS Scene

Remote Sensing Extent of Usage Does the common user have access to remote sensing technology?
Are Farmers using remote
sensing to monitor the drought…
Commodity Brokers?
Did First Responders use remote sensing
during the Waldo Canyon fire?
Are Foresters using remote sensing to track the Emerald
Ash Borer?
Has the Image Processing Promise has Stalled? Large Desktop Applications (toolkits) will never reach the common user
Mainframes & Command Line
Workstations & Menus
PCs & GUIs
It’s time for a new approach
Computing has Evolved
Image Processing
has not
Unlike Word Processing, One
Size Does NOT fit all
Jack is Right The Cloud is breaking down barriers to accessing content and functionality
The Cloud can “un-stall” the Promise of Remote Sensing
ArcGIS Online provides: • Content management in an elastic
cloud • Easy integration with ArcGIS server • Discovery and view of thousands of
map services • Users easily create their own services • These services can then be directly
accessed by all of the Esri web and mobile apps.
The Alchemy of Transformation The Cloud supports technological convergence and collaboration

ArcGIS Is A Powerful Platform For Image Processing Visualization, Analysis, Feature Extraction and Management
Simplifies Workflows and Automates Processing
Extraction
Dynamic Mosaicking
Visualization Analysis
Any Imagery
Massively Scalable
Automatic Processing
Highly Accurate
Advanced Remotely Sensed Content
Imagery for Visualization Emphasis on geospatial precision and high quality representation
Map Backdrop Digitizing Features
Content-as-a-Service (CaaS)
• Pictometry • Bing • Digital Globe*
Imagery for Analysis Support for scientific methodologies and techniques for understanding
Water Quality and Runoff Analysis Vegetation Health and Brownfields
Change Detection and Analysis
Imagery for Extraction of Features Spectral and Spatial processes to assign attributes to features
Landcover Mapping
Target Identification
Improvements in 10.1 – Quality Visualization
• Smarter rendering defaults - Looks good when you view it - No more black images - Default rendering is metadata driven
• New Image Stretching for quality - Gram-Schmidt pan-sharpening - Interactive stretching
• Dynamic Creation of “Smart Layers”
- Reads Sensor Data - Populates catalog with possible derived
products
Imagery Precision – Rectification and Mensuration
• Correction based on Rational Polynomial Coefficients (RPC)
• Correction based on Rigorous Sensor Models
• DEM Library for orthorectification • Auto-Tie for image to image precision • Certified Mensuration Capability (MSP – US
Defense)
Imagery Precision – Auto Registration Tool Uses photogrammetry and spectral matching to automatically find control
Feature Extraction Using Image Segmentation*
1. Original Image 2. Superpixel Segmentation 3. Extract geometry within user-defined region 4. Propagate classification to rest of image
(1) (2) (3) (4) It is easier to classify components of an object based on their logical segments

Mosaic Datasets are the Core of ArcGIS for Imagery
• Managed Content - Imagery and rasters - Associated metadata - Empowers Workflow Efficiency
• Dynamic Display and Analysis - Basic functionality becomes fully automatic - Embeds Knowledge for User Defined Processing - Simplifies imagery for end-users
• Seamless Approach for Imagery - Region based processing versus file - Virtual Mosaicking as a service - Saves time and effort; Improves Productivity
A powerful construct for managing big imagery data

ENVI Tools “Supercharge” ArcGIS for Imagery
ENVI’s interoperability and integration with ArcGIS give users advanced
image analysis, streamlined workflows, and extensive remote
sensing data support. Results are easily ingested back into their GIS
Contextual
Defining Signatures for Feature Extraction There are three basic types of signatures that can be used for extraction
Spatial Spectral
GeoProcessing Tools for Imagery & Spatial Analysis
Density and Proximity Tools aggregate extracted features into logical groupings.
Groupings are symbolized based on their density and displayed on the map.
